The inverse of -9n is dividing by -9.

Answer:
the answer is 2
Step-by-step explanation:
add -4x and -6x and the answer is -10x bc they are both negative x. then divide both -10x and -20 by -10 so that it is x by itself on one side and 2 on the other so its 2=x :)
Answer:
x=5
Step-by-step explanation:
4x + 8 = 28,
it's rather straight forward,
you would subtract 8 from the left side,
doing the same on the right.
now you have
4x = 20
x= 20/4
x=5
hope this helps.
Answer
After the 10 years with accrued interest, there will be roughly $1,552.92 in the account.
Explanation
Using the given equation A = P(1 +r)^t
We are given that our initial start is $500.
P = 500
We are further told that the percentage interest gained is 12%, so we need to convert this into a decimal to be able to work with it.
12% / 100% = 0.12
r = 0.12
t is then our time in years
t = 10
A = 500(1 + 0.12)^10
A = 500(1.12)^10
A = 500(3.1058)
A = 1,552.92
After the 10 years with accrued interest, there will be roughly $1,552.92 in the account.
